b90503fdf5 Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based 
on defines passed in from osg::StateSet::setDefine(..).

2d41cbd0cf Removed OSG_USE_BOUND and associated osg::Bound adapter class to avoid problems with BoundingBox::expandBy/expandByRadius() implementation choosing a null BoundingBox from 
the osg::Bound class causing crashes.

e70acf4c51 From Pjotr Svetachov, "I stumbled on a little bug with the new drawables. I was distributing points data into different drawables that I used in a LOD later. When simplifying the system to not use geodes anymore I came upon the following bug: 
If Drawable::getBoundingBox would compute an invalid bounding box (if it was for example empty) it would make a bounding sphere with a infinite radius which counts as a valid sphere in osg.

Attached is a small fix."

20b9f3ff88 Added Node::asDrawable() and Node::asGeometry() methods to provide a low cost way of casting a node to Drawable and Geoemtry. 
Changed the Group::computeBound() method so that it takes account of the a Drawable's BoundingBox.

b2c7bacfe9 From Farshid Lashkari, "As discussed, I've added the ability to handle Drawable objects within the NodeVisitor class. Here is an overview of the changes: 
- Added apply(Drawable) and apply(Geometry) to NodeVisitor

- Added accept(NodeVisitor) method to Drawable/Geometry

- Added traverse(NodeVisitor) to Geode which calls accept(NodeVisitor) on all Drawables

- Updated CullVisitor to use new apply(Drawable) to handle drawables. The apply(Billboard) method still manually handles the drawables since it is depends on the billboard settings. I needed to disable the traverse within billboard to prevent duplicate traversal of drawables.

- Update other osgUtil node visitors (GLObjectsVisitor, IncrementalCompileOperation, ..) to use new apply(Drawable) method.

5597248895 Introduced new scheme for setting up which version of OpenGL/OpenGL ES the OSG is compiled for. 
To select standard OpenGL 1/2 build with full backwards and forwards comtability use:

  ./configure
  make

OR

  ./configure -DOPENGL_PROFILE=GL2

To select OpenGL 3 core profile build using GL3/gl3.h header:

  ./configure -DOPENGL_PROFILE=GL3

To select OpenGL Arb core profile build using GL/glcorearb.h header:

  ./configure -DOPENGL_PROFILE=GLCORE

To select OpenGL ES 1.1 profile use:

  ./configure -DOPENGL_PROFILE=GLES1

To select OpenGL ES 2 profile use:

  ./configure -DOPENGL_PROFILE=GLES2


Using OPENGL_PROFILE will select all the appropriate features required so no other settings in cmake will need to be adjusted.
The new configuration options are stored in the include/osg/OpenGL header that deprecates the old include/osg/GL header.

68f37c4dcb From Tim More and Robert Osfield, implementation of ARB_timer_query based GPU timing stats syncronization. 
Initial email from Tim : "I've implemented using a timestamp, available with ARB_timer_query and OpenGL 3.3, to gather GPU stats. This is nice because it can accurately fix the GPU draw time with respect to the other times on the stats graph, rather than having to estimate the wall time of the end of GPU drawing. This also prevents anomalies like the GPU phase starting before the draw phase..."
Changes to Tim's submission by Robert:  Removal of need for swap buffer callback in ViewerBase.cpp, by
integrating a osg::State::frameCompleted() method that does the stats timing collection.  Introduction of a
GraphicsContext::swapBuffersCallbackOrImplementation() method that calls the State::frameCompleted() and
the swap buffers callback or the swapImplementation as required.
